Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.

1994 Group

The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year.
The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.

Role

The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".

Aquarium (Aqua album)

Aquarium is the debut studio album by Danish-Norwegian band Aqua. The album was released in Scandinavia on 26 March 1997 and in the United States on 9 September 1997. Although the group had been together for three years under their original name Joyspeed, their only release under that name was a single called "Itzy Bitsy Spider". The album is best known for including the successful singles "Barbie Girl", "Doctor Jones" and "Turn Back Time", the first of those being a huge hit across the globe. (The album was preceded by the two singles "Roses Are Red" and "My Oh My", with the latter re-released in 1998.)

The album's third single, "Barbie Girl" brought the group to international attention after reaching number one in both Denmark and Norway, as well as across Europe and in Australia and New Zealand. It would later peak at number 7 in the US. Its success helped the album reach number one in both the group's home countries, and make the top 10 in the UK and US. While not selling as highly "Barbie Girl", the album's fourth single "Doctor Jones" was released in late 1997/early 1998 and became a number one in Denmark, Norway, Australia and the UK. "Turn Back Time" would later give the group their third consecutive number one single in the UK, despite only reaching number 16 in Denmark. The final single, "Good Morning Sunshine" failed to chart highly and was only released in select regions like the earlier "Lollipop (Candyman)", the group's only other song to chart in the US. The album has sold 14 million copies worldwide.

The popular story behind the name "Aquarium" is that it was inspired by the Budapest street Leningrad pub "The Aquarium" and suggested by one of the band members. However, Grebenshikov has given differing stories in interviews, suggesting alternately that it came through band word association sessions or was inspired a glass aquarium-like building.
